Frequently asked questions

What is Sylfirm X?

A radiofrequency microneedling device with different energy modes.

Is Sylfirm X a pigment-removing laser?

No. It uses radiofrequency through microneedles, not laser light. Its role in pigmentation care depends on assessment.

How many sessions will I need?

The number of visits and spacing are personalized. We discuss a starting plan and review your response before recommending further treatment.

Can I combine it with another treatment?

Tell the clinic what you have recently had and what you are planning. Combining procedures is a separate decision; it depends on your skin, the products and the time available for recovery.
